TPS65561RGTR TI Power Management IC | 16-VQFN(3x3) | 4.5V-18V Input, 3A Output

Product Overview

The TPS65561RGTR from Texas Instruments is a high-efficiency, synchronous step-down (buck) converter designed for a wide range of applications. It integrates a 3A, 0.1Ω high-side and 0.08Ω low-side MOSFET, enabling high efficiency and compact design. The device operates from an input voltage range of 4.5V to 18V, making it suitable for 5V, 9V, 12V, and 15V bus voltages. The output voltage is adjustable from 0.8V to 6V, with an accuracy of ±1%. The switching frequency is fixed at 500kHz, allowing for small external components. The TPS65561RGTR is available in a 16-pin VQFN (3x3mm) package, ideal for space-constrained applications.
